Quick Step Floors' Laurens De Plus and Petr Vakoc were hit by a truck while training in South Africa.

The duo was on a training ride with Bob Jungels when a truck came from behind, hit them and send them to the ground. Jungels came out unscathed.

Both riders were conscious the whole time and were attended right away by team trainer Koen Pelgrim and were soon taken to the Mediclinic Nelspruit. De Plus was diagnosed with multiple abrasions and a minor pulmonary and kidney contusion while Vakoc's scans revealed several fractured vertebrae, which will require surgery that will be performed later on the day.

"The three of us were out training when suddenly I heard a loud noise and then in the following second I saw Laurens and Petr on the ground," said Jungels about the crash. "I did not see the truck coming from behind, but it must have hit them with the left front mirror or even the front left part.

"I ran to them and could see they were injured, so I did not dare to move them. A lady who was on the side of the road came and helped us, calling the ambulance, while our trainer Koen and I talked with them. It was really tough to see them like that and I hope they will get over this difficult moment soon. I wish them a fast recovery."
